“…Among demographic factors, higher age was most frequently associated with poorer smell, with seven studies reporting this association . Two studies did not find any association between age and olfactory dysfunction . Within CRS‐specific factors, a higher Lund‐Mackay (LM) computed tomography (CT) score was most frequently associated with poorer smell with 11 studies reporting this relationship .…”

Objective Many studies have reported that olfactory dysfunction frequently occurs in chronic rhinosinusitis (CRS) populations; however, the prevalence and degree of olfactory loss has not been systematically studied. The aims of this study are to use combined data to report the prevalence of olfactory dysfunction and to calculate weighted averages of olfactory test scores in CRS patients. Data Sources A search was conducted in PubMed and Scopus, following the methods of Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Review Methods Studies reporting the prevalence of olfactory dysfunction using objective measures or olfactory test scores using validated scales were included. Results A total of 47 articles were included in systematic review and 35 in the pooled data analysis. The prevalence of olfactory dysfunction in chronic rhinosinusitis was found to be 30.0% using the Brief Smell Identification Test, 67.0% using the 40-item Smell Identification Test, and 78.2% using the total Sniffin’ Sticks score. Weighted averages ± standard deviation of olfactory test scores were 25.96±7.11 using the 40-item Smell Identification Test, 8.60±2.81 using the Brief Smell Identification Test, 21.96±8.88 using total Sniffin’ sticks score, 5.65±1.51 using Sniffin’ Sticks threshold, 9.21±4.63 using Sniffin’ Sticks discrimination, 9.47±3.92 using Sniffin’ Sticks Identification, and 8.90±5.14 using the questionnaire for olfactory disorders-negative statements. Conclusion In chronic rhinosinusitis populations, a significant percentage of patients experience olfactory dysfunction and mean olfactory scores are within the dysosmic range.

“…4,[11][12][13][14] Initial studies used semiquantitative olfactory cleft grading systems and/or only examined limited aspects of olfaction. Results of these studies indicated that opacification of the olfactory cleft was a better predictor of olfactory loss than opacification of the sinuses proper.…”

“…neurosensory involvement (Litvack et al, 2009a). The value of preoperative olfactory function and/or nasal polyposis as predictors of postoperative olfactory recovery has since been replicated by several other studies (Pade and Hummel, 2008;Soler et al, 2010;DeConde et al, 2015;Kim et al, 2015;Andrews et al, 2016). Moreover, these two variables have also been shown to be independent preoperative predictors of postoperative improvements in QOL outcomes (Katotomichelakis et al, 2014).…”

“…Individuals demonstrating the greatest olfactory benefit were those with preoperative evidence of partial anterior ethmoid opacification. The authors provided a limited explanation for this finding, speculating only that the olfactory impairment in such individuals may have been more conductive in nature and, therefore, more amenable to surgical intervention (Kim et al, 2015).…”

Despite garnering minimal attention from the medical community overall, olfaction is indisputably critical in the manner in which we as humans interact with our surrounding environment. As the initial anatomical structure in the olfactory pathway, the nasal airway plays a crucial role in the transmission and perception of olfactory stimuli. The goal of this chapter is to provide a comprehensive overview of olfactory disturbances as it pertains to the sinonasal airway. This comprises an in-depth discussion of clinically relevant nasal olfactory anatomy and physiology, classification systems of olfactory disturbance, as well as the various etiologies and pathophysiologic mechanisms giving rise to this important disease entity. A systematic clinical approach to the diagnosis and clinical workup of olfactory disturbances is also provided in addition to an extensive review of the medical and surgical therapeutic modalities currently available.

Do Sinus Computed Tomography Findings Predict Olfactory Dysfunction and its Postoperative Recovery in Chronic Rhinosinusitis Patients?

Abstract: Our results can give support to the combined use of the butanol threshold and sinonasal CT findings in the evaluation of olfaction in CRS patients and help us counsel the patients about the likelihood of postoperative olfactory recovery.
